Hi everyone. I am adding a basement bathroom and have a question about running the new supply lines. The main floor bathroom is directly above so I have good access to the existing copper. Initially, I had planned to just T off with new copper. After reading a little about Pex I thought it would be so much easier to run Pex lines off the existing copper rather than build up the necessary maze of new copper lines. Does this sound like it makes sense? Are there special fittings to join Pex to copper lines? I could solder all the copper together if I have to. It just sounds so much easier to run flexible plastic lines. Thanks for any advice.
